Remove "static:" element type from animation-test-helpers.js

LayoutTests/animations/resources/animation-test-helpers.js

 /* This is the helper function to run animation tests:
 
 Test page requirements:
 - The body must contain an empty div with id "result"
 - Call this function directly from the <script> inside the test page
 
 Function parameters:
     expected [required]: an array of arrays defining a set of CSS properties that must have given values at specific times (see below)
     callbacks [optional]: a function to be executed immediately after animation starts;
                           or, an object in the form {time: function} containing functions to be
                           called at the specified times (in seconds) during animation.
     trigger [optional]: a function to trigger transitions at the start of the test
 
     Each sub-array must contain these items in this order:
     - the time in seconds at which to snapshot the CSS property
     - the id of the element on which to get the CSS property value [1]
     - the name of the CSS property to get [2]
     - the expected value for the CSS property
     - the tolerance to use when comparing the effective CSS property value with its expected value
 
     [1] If a single string is passed, it is the id of the element to test. If an array with 2 elements is passed they
     are the ids of 2 elements, whose values are compared for equality. In this case the expected value is ignored
-    but the tolerance is used in the comparison. If the second element is prefixed with "static:", no animation on that
-    element is required, allowing comparison with an unanimated "expected value" element.
+    but the tolerance is used in the comparison.
 
     If a string with a '.' is passed, this is an element in an iframe. The string before the dot is the iframe id
     and the string after the dot is the element name in that iframe.
 
     [2] If the CSS property name is "webkitTransform", expected value must be an array of 1 or more numbers corresponding to the matrix elements,
     or a string which will be compared directly (useful if the expected value is "none")
     If the CSS property name is "webkitTransform.N", expected value must be a number corresponding to the Nth element of the matrix
